Freel Flying Wing
The Freel Flying Wing was an experimental glider designed and built in the United States during the 1930s. Design and development The Freel Flying Wing was the creation of Charles Lewis Freel (b. 1916). As a student of San Diego High School, in San Diego, California, Freel learned about aerodynamics under the instruction of LeTain Kittredge, in the aircraft rigging/woodshop class. Before his graduation, Freel designed a 36-inch experimental Free flight (model aircraft), free flight model of a flying wing glider. The model flew well enough to justify moving to a full size piloted glider. In 1933, construction was begun at the San Diego High School woodshop, on a 52-foot span flying wing glider. It was completed in 1937 and licensed with identification mark 18131. Elevons were mounted on the trailing surface and were controlled via a unique worm drive. Several flights were made by Kittredge and Freel over hillsides near San Diego. The glider suffered from poor directional control ...

Charles Lewis Freel
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (wikt:Appendix:Proto-Indo-European/ǵerh₂-">ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain." An old man has been worn away and is now grey with age. In some Slavic languages, the name ''Drago (given name), Drago'' (and variants: ''Dragom ...

San Diego High School
San Diego High School (SDHS) is an urban public high school located on the southern edge of Balboa Park, San Diego, California, Balboa Park in San Diego, California, United States. It is the oldest high school in the San Diego Unified School District, one of the oldest public schools in California, and the oldest in the state still on its original site. History Russ High (1882–1907) By 1881, the population of William Heath Davis, William Heath's and Alonzo Horton's Downtown San Diego, New San Diego, swelled to over 2,500 which quickly filled up the exisiting schools and neccecitated the construntion of another. Voters then approved $12,000 to construct the new school, which came to be named Russ School after lumberman Joseph Russ, who donated the lumber to build the school. The school was built in the Italian Villa style with a low-hip roof, ironwork parapet, and open-bell tower. It consisted of two stories and eight rooms. The school opened on August 14, 1882 to a class of 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego, California
San Diego ( , ) is a city on the Pacific coast of Southern California, adjacent to the Mexico–United States border.

Free Flight (model Aircraft)
Free flight is the segment of Model aircraft, model aviation involving aircraft with no active external control after launch. Free flight is the original form of hobby aeromodeling, with the competitive objective being to build and launch a self controlling aircraft that will consistently achieve the longest flight duration over multiple competition rounds, within various class parameters. Description The essence of free-flight is that the aircraft have no need for external control, for instance by radio. Aircraft of this type have been flown for over two centuries. They are designed to be inherently stable in flight; if disturbed by a gust of wind or a thermal current they will return automatically to stable flight. Their stability is achieved by a combination of design and trim, - the relationship between centre of gravity, wing and tailplane incidence and rudder setting. With their much lower wing loading, free-flight aircraft fly much more slowly than the engine-powered ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worm Drive
A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). Its main purpose is to translate the motion of two perpendicular axes or to translate circular motion to linear motion (example: band type hose clamp).The two elements are also called the worm screw and worm gear. The terminology is often confused by imprecise use of the term ''worm gear'' to refer to the worm, the worm wheel, or the worm drive as a unit. The worm drive or "endless screw" was invented by either Archytas of Tarentum, Apollonius of Perga, or Archimedes, the last one being the most probable author.Witold Rybczynski, '' One good turn : a natural history of the screwdriver and the screw''. London, 2000. Page 139. The worm drive later appeared in the Indian subcontinent, for use in roller cotton gins, during the Delhi Sultanate in the thirteenth or fourteenth centuries.Irfan Habib''Economic History of M ...

Consolidated Aircraft Corporation
The Consolidated Aircraft Corporation was founded in 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors.Yenne 2009, p. 15. Consolidated became famous, during the 1920s and 1930s, for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies. Equally famous was the B-24 Liberator, a heavy bomber which, like the Catalina, saw action in both the Pacific and European theaters. In 1943, Consolidated merged with Vultee Aircraft to form Consolidated-Vultee Aircraft, later known as Convair. The Los Angeles-based Consolidated Steel Corporation is not related.

Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose gliding flight, free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by Motor glider, self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit lift (soaring), meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such a ...
